Fox won the night with adults 18-49, and ABC won with viewers. CBS was in second place both with viewers and adults 18-49.

The premiere of Trauma was not so good for NBC with only a 2.3/6 rating/share with adults 18-49. House was tops for the night with a 5.7/15, followed by The Big Bang Theory and its 5.1/12.

Trauma did worse than Heroes (2.5/6) with adults 18-49, and it was Heroes' lowest-ever 18-49 rating for an original episode.

Retentionistas will have a field day with the premiere of Lie to Me, which only pulled a 2.9/7 adults 18-49 rating/share out of House.

The Big Bang Theory is now overshadowing Two and a Half Men in 18-49 (5.1 vs. 4.7) but Men held a narrow edge with total viewers (13.64 vs. 13.02). TBBT also had a healthy lead over Men with adults 18-34 (3.6 vs. 2.9) Here are the CBS blurbs about TBBT:

At 9:30PM, THE BIG BANG THEORY was first in adults 25-54 (6.0/13), adults 18-49 (5.1/12), adults 18-34 (3.6/12) and second in both households (7.8/12) and viewers (13.02m). THE BIG BANG THEORY was up +3% in adults 25-54 (from 5.8/12), +9% in adults 18-49 (from 4.7/11), +20% in adults 18-34 (from 3.0/08) and added +60,000 viewers (from 12.96m) from last week's premiere.

This was THE BIG BANG THEORY's best delivery in viewers, adults 25-54, adults 18-49 and adults 18-34. This is the second straight broadcast THE BIG BANG THEORY posted series highs in viewers, adults 25-54 and adults 18-49. THE BIG BANG THEORY built on its TWO AND A HALF MEN lead-in by +4% in adults 25-54, +9% in adults 18-49 and +24% in adults 18-34.

The good news for Castle fans is it again beat The Jay Leno Show (2.3 vs. 1.8), but some Dancing With the Stars overrun is probably included, which would be stripped out in the finals. As it stands, Castle had a 2.5/6 with adults 18-49 from 10-10:30p, and a 2.1/6 from 10:30-11p.

Since it's been a crazy day for us, I'm posting in "Holly's" comments from the comment section:

CBS did well. AOP dropped slightly from last week, but no more than would be expected from a premiere (maybe less, since it only lost 0.1 in the demo). TBBT hit another high and actually beats Men in the demo. Looks like CBS made a good choice in moving that to 9:30. Miami didn’t lose much from last week either, so all in all, a very good Monday for them.

House took the expected fall from last week, but still did really well. It’s still slightly above what it was doing last fall. I don’t think FOX is breaking out the champagne for Lie To Me’s performance, but they can’t be upset about it either. If it can stay close to a 3.0, it will be just fine regardless of what House gets.

ABC might not be as happy. Dancing is down quite a bit from last year. It’s still OK, but not nearly as strong as it had been. Castle stayed steady from last week, so no complaints there.

NBC…well…ouch. Heroes can’t pull a 3 and is probably more of a liability than an asset. I suppose Trauma premiered about as well as could be expected given the state of NBC, but it was still bad.

*Fast Affiliate Ratings: These first national ratings, including demographics, are available at approximately 11 AM (ET) the day after telecast, and are released to subscribing customers daily. These data, from the National People Meter sample, are strictly time-period information, based on the normal broadcast network feed, and include all programming on the affiliated stations, sometimes including network programming, sometimes not. The figures may include stations that did not air the entire network feed, as well as local news breaks or cutaways for local coverage or other programming. Fast Affiliate ratings are not as useful for live programs and are likely to differ significantly from the final results, because the data reflect normal broadcast feed patterns. For example, with a World Series game, Fast Affiliate Ratings would include whatever aired from 8-11PM on affiliates in the Pacific Time Zone, following the live football game, but not game coverage that begins at 5PM PT. The same would be true of Presidential debates as well as live award shows and breaking news reports.

Rating: Estimated percentage of the universe of TV households (or other specified group) tuned to a program in the average minute. Ratings are expressed as a percent.

Share (of Audience): The percent of households (or persons) using television who are tuned to a specific program, station or network in a specific area at a specific time. (See also, Rating, which represents tuning or viewing as a percent of the entire population being measured.)

Time Shifted Viewing – Program ratings for national sources are produced in three streams of data – Live, Live+Same Day (Live+SD) and Live+7 Day. Time shifted figures account for incremental viewing that takes place with DVRs which are currently in approximately 24.4% of all U.S. TV households. Live+Same Day (Live+SD) include viewing during the same broadcast day as the original telecast, with a cut-off of 3:00AM local time when meters transmit daily viewing to Nielsen for processing. Live+7 Day ratings include incremental viewing that takes place during the 7 days following a telecast.
